Dynamic balance process method of carbon fiber composite transmission shaft tube and combined dynamic balance clamping hoop

The invention discloses a process method for achieving dynamic balance of a carbon fiber composite transmission shaft and a used combined dynamic balance clamping hoop device. The dynamic balance device comprises a clamping hoop, bolts, nuts, spring gaskets, balancing weights and balancing weight set screws. The clamping hoop is composed of four quarter round clamping hoop bodies which are connected through the bolts, the nuts and the spring gaskets. The integrated round clamping hoop is formed on a carbon fiber composite tube in the circumferential direction. Threaded holes used for fixing the balancing weights are uniformly distributed in the circumference of the round clamping hoop. The device is simple in structure, the carbon fiber composite transmission shaft can be dynamically balanced by adopting a weight increment method or a weight decrement method by means of the process method, in addition, operation is convenient when the axial and circumferential positions of the balancing weights are adjusted, drilling weight-decrement is not needed in the carbon fiber composite transmission shaft, the balancing weights do not need to be bonded to the shaft, and dynamic balance of the carbon fiber composite shaft tube can be easily and effectively achieved.
